A cover letter has one job: to give the reader a reason to open your resume with interest. It is not a repeat of your resume in sentence form. It is the place to explain why you are applying to this particular company, and why your experience fits what they need.
The standard structure
Professional cover letters follow a recognizable layout, and recruiters expect it. From top to bottom, you will normally find:
- Your contact details (name, address, email, phone).
- The place and date.
- The recipient's name, title, and company.
- A subject line that names the role you are applying for.
- A salutation, ideally with the name of the person who will read it.
- The body of the letter, in two or three paragraphs.
- A closing phrase and your signature.
The Cover Letter Builder applies this structure for you: sender details, place and date, recipient, an underlined subject line, a justified body, and a closing phrase. You concentrate on the words, not the formatting.
What to write in each paragraph
The opening
Start with something specific, not I am writing to apply for the position. Mention the role, and in one sentence say what draws you to this company or to this type of work. A concrete detail, such as a product you use or a project you admire, shows you did your research.
The middle
This is where you connect your experience to the job. Pick two or three achievements that match what the advertisement asks for, and describe them with results when you can: what you did, and what changed because of it. Resist the temptation to list everything; the resume already does that.
The close
End by stating what you would like to happen next, such as a conversation or an interview, and thank the reader for their time. Keep the tone confident and polite, without pleading or over-selling.
Tailor every letter
A generic letter is easy to recognize and easy to discard. Reread the job advertisement, note the two or three qualities it emphasizes most, and make sure your letter speaks to them. Changing the company name is not tailoring: the substance of at least one paragraph should be different for each application.
Changing careers or applying for your first job
If you are moving into a new field, use the letter to explain your motivation and to highlight skills that transfer, such as organization, communication, or problem solving. If you are applying for an internship or a first job, focus on your education, projects, volunteer work, and the qualities your referees would mention. Employers know you have little experience; what they look for is clarity and genuine interest.
Mistakes that cost you the interview
- Spelling and grammar errors. Read the letter aloud before sending it.
- Writing more than one page. Short letters get read.
- Addressing the wrong person or company, a classic mistake when reusing a letter.
- Repeating the resume line by line.
- Sending an editable file when the employer expects a PDF.

A letter works best with a resume built in the same spirit. The Resume Builder produces a clean two-column resume, and the Merge PDF tool can combine the resume, the letter, and your diplomas into a single file when a job portal accepts only one attachment.

Frequently asked questions
How long should a cover letter be?+
One page at most. Two or three short paragraphs are usually enough to say why you are applying and why your experience fits.
Should I write a cover letter if it is not required?+
If you have the chance to include one, it is often worth it, because it lets you explain motivation and context that a resume cannot show.
Is my letter stored anywhere?+
The text you write stays in your browser until you export the letter as a PDF; the builder does not send it to a server.
Which file format should I send?+
A PDF is the safest choice: it keeps the layout identical on every device and cannot be altered accidentally.
